1. Installation ProcessPro transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary hardware to install the transmitter. This manual includes complete panel mounting instructions.Field mounting requires a separate mounting kit. The 3-8050 Universal kit enables the transmitter to be installed virtually anywhere. Detailed instructions for fi eld installation options are included with the 3-8050 Universal kit.

1.1 Panel Installation 1. The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel cutout, an adhesive

template is provided as an installation guide. Recommended clearance on all sides between instruments is 1 inch. 2. Place gasket on instrument, and install in panel. 3. Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument. 4. To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT RELEASE. Press quick-clips outward and remove.

3. Electrical Connections

Caution: Failure to fully open terminal jaws before removing wire may permanently damage instrument.

Wiring Procedure 1. Remove 0.5 - 0.625 in. (13-16 mm) of insulation from wire end. 2. Press the orange terminal lever downward with a small screwdriver to open terminal jaws. 3. Insert exposed (non-insulated) wire end in terminal hole until it bottoms out. 4. Release orange terminal lever to secure wire in place. Gently pull on each wire to ensure a good connection.

Wiring Removal Procedure 1. Press the orange terminal lever downward with a small screwdriver to open terminal jaws. 2. When fully open, remove wire from terminal.

Wiring Tips:• Do not route sensor cable in conduit containing AC power wiring. Electrical noise may interfere with sensor signal.• Routing sensor cable in grounded metal conduit will help prevent electrical noise and mechanical damage.• Seal cable entry points to prevent moisture damage.• Only one wire should be inserted into a terminal. Splice double wires outside the terminal.

VIEW Menu• During normal operation, ProcessPro displays the VIEW menu.• When using the CALIBRATE or OPTIONS menus, ProcessPro will return to the VIEW menu if no activity

occurs for 10 minutes.• To select the item you want displayed, press the UP or DOWN arrow keys. The items will scroll in a

continuous loop. Changing the display selection does not interrupt system operations.• No key code is necessary to change display selection.• Output settings cannot be edited from the VIEW menu.

• Proportional PulsingThe Open Collector output will generate a 100 mS pulse at the rate defi ned by settings in the CALIBRATE menu (see page 6) In the example below:• The output will be 0 pulses/min. at pH values less than 5.0.• The output will be 50 pulses/min. at 7.5 pH.• The output will be 100 pulses/min. at pH values above 10 pH.

3.3 Open Collector OutputThe Open Collector output can be used as a switch that responds when the process value moves above or below a setpoint, or it can be used to generate a pulsing signal with a rate proportional to the process value.

• Low:Output triggers when process variable is less than the setpoint. The output will relax when the process moves above the setpoint plus the hysteresis value.

• High:Output triggers when process variable is greater than the setpoint. The output will relax when the process variable moves below the setpoint plus the hysteresis value.

Provides a maximum 25ºC offset to match temperature measurement to external reference.

Applies a linear offset to the pH measurement. The ideal value is the average pH of your application. (A sample of your application at process temperature is recommended.)

Applies a slope to the pH measurement. The slope value and the standard value must be at least 2 pH units apart.The ideal values are the minimum and maximum values of your process.

Select the minimum and maximum values for the 4-20 mA Current loop output.

Select pH or Temperature as the source for the Open Collector Output.

Select the mode of operation for the Open Collector output: High, Low or proportional Pulse.The signal may be disabled if not in use.

In Low or High Mode, the Open Collector output will be activated when the pH reaches this value.

In Low or High mode, the Open Collector output will be deactivated at Setpoint ± Hysteresis, depending on High or Low Setpoint selection. (See details on page 4.)

If the output is in PULSE mode, set the start and end point of the range and also set the maximum pulse rate. (The maximum PULSE rate setting is 400 pulses per minute.)

The combined Output Range and Pulse rate settings shown here indicate:"Start pulsing when the pH value is 4 and increase the pulse rate up to the maximum of 120 pulses per minute when the pH value reaches 8"

Use this “note pad” to record important dates, such as annual recertifi cation or scheduled maintenance.
